Installation
To install the Nyquist NQ-A4XXX Power Ampliers:
1. Ensure the POWER switch is in the off position.
2. This product requires a connection to a Mains circuit with a
maximum of a 20A breaker.
3. Connect a Cat-5 type cable into the amplier’s Ethernet port and
ensure the other end of the cable is correctly connected to your
network.
4. Set each of the two AmplierMode switches to the desired setting.
Each of the two internal ampliers (A+B and C+D) can be congured
for single-channel bridged mode (aka bridged-tied load) operation
for 70V/25V/8Ω applications, or 2-channel operation for 25V/8Ω/4Ω
applications. The Amplier Mode switch is used in conjunction with the
Bridged Signal routing setting in the system console.
BridgedMode is typically used when higher power, single channel
operation with a high impedance loudspeaker load is desired. A
typical use-case would be for 70V or 25V loudspeaker runs, where
the total load is no less than 8Ω.
2-ChannelMode is typically used for 8Ω or 4Ω loudspeakers or 25V
loudspeaker runs. This mode allows the two amplier channels to
run independently.
In BridgedMode, Line Input 1 (or Line Input 3) is used as input. For
2-ChannelMode operation, Line Inputs 1 and 2 (or Line Inputs 3 and 4)
are used.
5. Connect the loudspeaker wires to the Amplier Output Terminals
(labeled A +/−, B +/−, C +/−, and D +/−) as appropriate for the
desired mode of operation ( ).see Figures 1 and 2
Bridged mode operation requires the speaker wires to be
NQ‑A4060‑G2, NQ‑A4120‑G2, NQ‑A4300‑G2
These networked Audio Power Amplifiers support a full range of
commercial paging, public address applications, and residential audio
applications, regardless of the venue size. The NQ-A4060, NQ-4120,
and the NQ-4300 can operate in 2-, 3-, or 4-channel mode, depending on
bridged mode congurations and application need.
Each networked audio power amplier is a half-rack 2RU high enclosure
containing a Class D audio power amplier, a universal switched-mode
power supply, an RJ45 network jack, a USB port, and pluggable Phoenix
style terminals for loudspeaker and Line-In connections. Optionally, Line-
In can be connected using the available RCA connectors.
